Definitions
- the invention relates to a plastic welding machine, in particular a hot air or hot wedge welding machine, for the integral connection of at least two layers, the welding machine welding tools, each having at least a pair of drive rollers and an electronic control device comprising a computer for temperature control of the welding tools and for setting and Control of the pressure of the drive rollers contains.
- Such a welding machine is essentially already known from DE 198 54 259 C2. It is a heat sealing machine in which two layers connected by a sewing seam are subsequently sealed by welding a tape.
- an electronic control device monitors all predetermined relevant welding parameters in order to ensure a certain weld seam quality.
- the actual sequence control is carried out by an operator during the welding process (for example by actuating a foot pedal). If, for example, two layers are to be connected to each other, which contain a curved section, the respective operator changes the welding parameters when the curved section is reached by changing the position of the foot pedal, so that the normal speed of the two drive rollers is reduced and, depending on this, for example the temperature of the welding tools can be changed. When the end of the curve is reached, the position of the foot pedal is then changed in order to increase the speed of the drive rollers and to increase the temperature of the welding tools.
- a disadvantage of these known welding machines is, inter alia, that the detection of the beginning and end of the curve is relatively error-prone and depends, among other things, on the current state of the person operating the machine.
- the invention has for its object to provide a plastic welding machine in which the sequence control of the welding process is largely independent of the operator of the welding machine.
- the invention is essentially based on the idea of carrying out the sequence control of the welding process without the intervention of an operator only with the aid of a sequence program (welding program) stored in a memory of the control device.
- a sequence program welding program
- the entire area of the two layers to be welded is divided into several welding sections before the welding process is carried out, with the (primary) welding parameters to be observed for each welding section, such as the temperature of the welding tools or the welding medium, the normal speed of the two or one of the two drive rollers, the roll contact pressure etc. can be determined.
- the parameters corresponding to these settings are stored in a data memory of the control device, to which the sequence program has access.
- the control device of the welding machine uses a position measuring system to determine the distance that has already been welded and compares these values with a default value that characterizes the start of a new welding section. If the preset value is reached, the sequence program automatically causes the welding parameters characteristic of the new welding section to be set.
- a total of three welding sections would preferably be defined, the welding parameters then being specified such that the drive roll synchronously in the two straight welding sections, while in the curved welding section the welding parameters are selected in such a way that the upper roll runs somewhat faster in order to compensate for the additional values of the upper layer.
- the welding sequence therefore takes place essentially without the intervention of an operator.
- the lengths of the welding sections are determined beforehand and then repeated very precisely with each welding process.
- the welding machine according to the invention can therefore be used particularly advantageously if recurring identical parts are to be produced.
- a complete garment can be made partially automated, in which e.g. ten different welds, a corresponding number of welding programs with different parameters and distances must be taken into account and which run repeatedly in a sequence. This means that a complete batch of a certain size can be processed, in which the operator only has to insert the weld metal into the welding machine in a predetermined sequence, give the start signal and only has to guide it in the correct direction.
- the secondary welding parameters are essentially parameters that determine the setting of the acceleration and braking behavior as well as the length of the start delay to compensate for the heating process of the welding tools (roller parameters) and parameters that determine the formation of the respective nozzle or the Wedges (narrow, medium or wide) affect (welding tool parameters).
- control device comprises a memory in which information which can be displayed on a screen of the welding machine and the comments associated with the current welding program can be stored and / or reflect settings of the welding tools (so-called notepad information). This information can be entered into the electronic control device, for example, when the respective sequence program is created.
- release information can also be assigned to the information shown, so that the corresponding sequence program is only activated when the respective operator presses the release button (e.g. a touch field on the screen).
- the measuring system of the plastic welding machine comprises at least one tachometer generator.
- Fig.l the block diagram of a hot air welding machine according to the invention.
- Fig.2-4 three examples of the use of the welding machine according to the invention.
- FIG. 5 shows an exemplary embodiment of a notepad function shown on the screen of the welding machine according to the invention.
- Fig.l 1 is a schematically illustrated hot-air welding machine (see also DE 198 54 259 C2 mentioned at the outset for the structure and functioning of such welding machines).
- the welding machine 1 comprises an electronic control device 2, which contains, among other things, a microcomputer 3.
- the control device 2 is connected to a control unit 4 with a screen 5.
- the welding machine 1 comprises an air heater 6, which is connected to a hot air nozzle 7, which is directed between the layers to be welded (not shown), and a roller pressure system, which has two opposite drive rollers 8, 9 for feeding the two layers and one over a compressed air line 10 comprises a compressed air cylinder 12 connected to a compressed air source 11.
- the compressed air cylinder 12 is operated via a controller 13, to which a servo valve 14 is assigned as an actuator.
- the servo valve 14 influences the pressure of the compressed air supplied by the compressed air source 11 via the line 10.
- a pressure sensor 15 serves to detect the actual pressure value, the signal of which is fed to the electronic control device 2 and the controller 13.
- the two drive rollers 8, 9 are each driven by their own motor 16, 17, which are each connected to the electronic control device 2 via a power unit 18, 19 and a controller 20, 21. To determine the output speed of the respective motor 16, 17, the latter is connected to a tachometer generator 22, 23, the measurement results of which are also fed to the control device 2 via a corresponding line 24, 25.
- the air heater 6 is connected to the compressed air source 11 via the compressed air line 10 and a branch line 26.
- a sensor 29 serves to record the actual value of the air quantity supplied to the air heater 6, the signal of which is fed to the control device 2 and the controller 27.
- the air heater 6 comprises an electrically operated heating element 30 which is operated via a controller 31 connected to the control device 2 and a power unit 32.
- a sensor 34 which is arranged in the connecting pipe 33 to the hot air nozzle 7 and is connected to the control device 2 and the controller 31, is used to determine the actual value of the hot air temperature.
- the electronic control device 2 also includes, among other things, a program memory 35 in which a sequence program (welding program) which controls the entire welding sequence of the welding machine 1 is stored, and a data memory 36 in which the data which can be called up by the sequence program are stored , Both the data and the sequence program can be via an interface and a line 37 is loaded into the control device 2.
- a program memory 35 in which a sequence program (welding program) which controls the entire welding sequence of the welding machine 1 is stored
- a data memory 36 in which the data which can be called up by the sequence program are stored , Both the data and the sequence program can be via an interface and a line 37 is loaded into the control device 2.
- welding sections with predetermined lengths are defined beforehand, within which the primary welding parameters, such as the temperature of the hot air, the feed speed of the two drive rollers 8, 9, the air quantity and the roller contact pressure should be constant.
- the microcomputer 3 of the control device 2 determines the distance traveled by the layers welded to one another during the welding process, in which the speed values of the motors 16, 17 measured by means of the tachogenerators 22, 23 are determined and evaluated.
- the control device 2 causes the welding parameters which are characteristic of the corresponding new welding section and are stored in the data memory 36 to be read out and the corresponding changes to be set.
- secondary welding parameters are also stored in the data memory 36 or another data memory before the actual welding process. These secondary welding parameters lead to settings of the welding machine 1 which do not change during the entire welding process.
- the secondary welding parameters are parameters that determine the setting of the acceleration and braking behavior as well as the length of the start deceleration (to compensate for the heating process of the welding tools) or parameters that determine the size of the hot air nozzle or in the case of a Hot wedge welding machine concern the wedge size, which can be narrow, medium or wide.
- FIG. 2 shows the welding of a straight lower layer, designated 38, with a round upper layer 39, as can occur, for example, when welding a sleeve.
- three welding sections 40-42 are defined.
- the motors 16, 17 must be controlled by the control device in such a way that the drive rollers 8, 9 rotate synchronously in the welding section 40.
- the motors 16, 17 are controlled in such a way that the upper drive roller 9 rotates somewhat faster than the lower drive roller 8 in order to compensate for the additional width of the upper layer 39.
- the two drive rollers 8, 9 have to rotate synchronously with one another again.
- the switching between the individual welding sections 40-42 is preprogrammed in terms of route.
- the upper layer 39 is "turned in” by hand to the lower layer 38 by the corresponding operator.
- FIG 3 shows the welding of two layers 43, 44, both of which are each provided with a curve.
- three welding sections 45-47 are defined. You can weld quickly in the welding section 45 (straight piece), i.e. the motors 16, 17 can cause a high rotational speed of the drive rollers 8, 9 and the temperature of the hot air can be relatively high. In the welding section 46 (area of the rounding), welding must be carried out more slowly, particularly for handling reasons, so that the speed of rotation of the drive rollers 8, 9 must be slower and the temperature of the hot air must be lower. The same applies to the welding section 47 for the welding section 47 (straight piece).
- three layers 48-50 are welded together.
- layer 48 is welded to layer 49 in a first operation, so that a weld seam 51 results.
- layer 50 is then connected to the layer consisting of layers 48 and 49.
- Three weld sections 52-54 are again defined. This results in a so-called T-joint in the welding section 53 due to the weld seam 51. In this welding section it is advisable to drive a little slower, a little hotter or with a different roller pressure.
- the invention is of course not based on the exemplary embodiments described. limits.
- another known displacement sensor can be used to measure the welding sections instead of a tachometer generator.
- the weld metal is provided with markings which are scanned by a sensor.
- Pressure sensor 17 motors, 19 power units, 21 controllers, 23 tachometer generators, 25 lines
